View Full Version : cutom corner "dots"

Ive been looking for something like this for a while. We found a few plastic toy things that look good, but they just dont work out (usually wont stay put) for some reason or another. I decided to make my own, the way I wanted them.

These will be 12" diameter circles, and will provide approxamitely 3" of 'curbing' to the insides of curves. They can be used on 90 degree corners, haripins, 45 corners, and Im going to try them out on the outsides of wide radius corners once I get enough to have them all over the track. If they dont work out/look good on the outsides, Ill come up with a similar part for that. I can actually use these on straight tiles as well, so I can create chicanes and racing line changes within the 33" RCP lane.

These should add quite a bit of variation to my layouts, as well as the most important thing, cleaning up the racing a lot. Ive talked with folks from other tracks who use 'dots', and they say that early apex wrecks are almost non-existent. Most of the bad wrecks on our track come when some one is following some one else closely, and the lead car clips the inside of a turn. Of course the lead car gets spun out right into traffic (typical RCP style :D) and the following car plows them at full speed. Ive seen front body clips broken, and tons of headlights fly out in this scenario. Im hopeful that these simple additions will keep the driving line a couple inches further away from the RCP walls, and if some one clips one too close, it will unsellte their car, as oppposed to stopping it in the track. There will still be wrecks at corners, so Im not expecting a magical solution to wrecks, but it should clean it up a lot.

Anyway, enough rambling, here are some pics (and a short clip) of one.

EDIT: I wish I could edit my title, since I can never spell correct on the first try, lol.

Looks like a good idea. Let us know how it works,

We have been using plastic dots for a little while. I personally like them depending on the line of the track. Sometimes they stick out just a little too much, especially if you are using a pan car... They have decreased the amount of crashes on the apex, and give you a better view of the clipping point using peripheal vision.

I would like if RCP would make a set for the corners, wide, hairpin, and 45 degree transition. Only an inch or 2 is needed... Curbing is much easier on the car than the foam barriers, especially if you are just trying to drive the line close... and touch and spin out. With the curbing (dots) you hit them, and would go a little wider instead of stopping. Also prevents the F1s from diving under the rails as much.

Sports authority has something like this, check near the soccer balls/Goalie equipment.

I think it's a great idea. :) As EMU said, dots are a lot more forgiving than the foam barriers with respect to racing lines. Dots that send the cars out wide instead of spinning them out would make Mini-Z racing a lot closer I think, as people could afford to battle harder without being scared of one minor clip turning them into lap traffic.

You can see our use of the dots in this video http://www.youtube.com/watch?v=Z5bZddjlxqk&fmt=18 Before the dot was there, a lot of people were hitting the bottom left apex. After the dot, nobody hit it during the race.

In this example, I think there is too much dot exposed... but 2 inches exposed around the corner should be perfect. Basically the way that hrdrvr has in his example...

Ian, Ill let you know how it goes. Thanks for the interest :D

Eugene, It would be nice if Kyosho or RCP came up with a standardized set of these that matched each corner set. It would be cool to see them at some sanctioned events. If they work out like Im hoping they will (as good as they have for you guys) then you will likely see them at my events atleast.

Thanks for posting the video. My dots have the ability to hang out like the one in the foreground of the vid (and still be attached to the wall) but I like the way they look when they are symetrical around the corner. I dont think 1" is going to make a huge difference, but in the example I posted, mine are 3" from the foam wall. There is a 2" flat spot, then the 1" tapered 'curb'. I dont think it sticks out too much, and I wanted it to stand out as a visual aid as well. Thats also why I chose white instead of red/pink/orange, as I dont want it to blend into the track or walls.


Dave, Ill be headed to Sports Auithority today. Something I could mod a little as opposed to fabbing from scratch may save me some time. The ones in EMUs action video look just like soccer dots!


Brian, If I can promote cleaner and more aggressive racing at the same time, then Ive hit a home run! :D

I didnt get a chance to get by sports authority, but I did make up a few more 'dots', and an outside run-off. Ill use it on the wide radius turns, as I like how they help maintain lane width.

Here are some pics of the 'dots' in various configurations.

I like the curbs close to the walls, so I tucked them down to the minimum. Heres an overview of a section of the track outfitted :D

I like your dots. Great idea. Did you purchase them already tapered like shown or did you do some modifications? I will check with our factory to see if we can manufacture a standerdized set to match the corner type. If we use an injection mold, it would be very expensive and would need to sell a few thousand to break even. Possibly there is a way to make them without making an injection mold. I will let you know.

Thanks,
John

John, I will contact you via email with a solution to injection molding.

John, I made these totally from scrath out of 1/4" birch plywood. I just cut the plywood cirlces, drilled out my holes, then tapered the edes with a 4" grinder. The soccer dots seem like the closest thing that is mass produced, and I believe those would be tapered as well. My method wouldnt be very good for mass production, but it was plenty easy to do for my track....easy enough, I may make some for the LHS if they are interested.

hrdrvr,

Could you post a dimensioned drawing for those of us who want to have a go at making some? Thanks,

Ian, Im sorry about the delayed reply. Ive been meaning to snap a few pics, as I didnt make any type of dimensional drawing for the 'dots', as I didnt think it was neccesary. If youd like me to make one for the outside run-offs, Im sure I would come up with it.

Once I got the 12" circle marked and cut, I just laid a set of four inside corners attached to each other over it, marked the holes, then cut them out with a hole saw. I didnt take any pics before painting, but this will give you an idea.

As you can see from that pic, I decided to paint the stripes on, and paint them a proper color :D They look a lot better in red, as well as being more appropriately sized.

I also snapped a couple of random shots to see how they changed the look of the track.

LMK what you guys think!

Oh, and BTW, if I were to make these over, Id probably make the 12" dots 11" or so. At 12" it barely blocks the next wall post hole, so you have the either rotate the corner so that its not symetrical, or leave the posts out. I decided to leave the post out, as you can see from some of the pics.
